If you buy a 4K make sure to pick up a PS4 Pro or XBox One X for some amazing eye candy games.
I bought an Xbox One X. That's why I'm shopping 4k TV's.

For broadcast, I've got DTV, and I'm not going to buy a 4K Package from them any time soon. My only concern is that the TV upscale decently so HD content doesn't look like crap on it. The guy at Best Buy tells me that won't be a problem, but if any of you have an HD broadcast package piping into a 4K TV, I'd love to know what you found.
For budget, I'm looking to stay under $1000, so I'm not shopping OLED or QLED at the moment. This one's just for the bedroom so I'm only looking at 49' models. When we buy a place in the next year or two, then I'll probably shop for a OLED in a larger size as well.
Here's the Sony I'm eyeing, the reviews seem solid and the one at the store looked great. Also it claims that it'll be Dolby compatible with a firmware update, which is great.
